The 1.5 million-square-foot office and retail development at 666 Fifth Avenue has been the subject of a number of record-setting deals. Kushner Companies bought the property for $1.8 billion in 2007, at the time the most ever paid for a single office building in the U.S.

After the 2008 global financial crisis struck, in early 2010 Kushner's $1.215 billion loan was sent to special loan servicer LNR, in which Vornado Realty Trust would later take a stake. Kushner split the retail space into two condominiums, selling the smaller, 36,473-square-foot space to Inditex, parent company of fashion brand Zara, for $324 million or $8,300 per square foot on a blended basis, the highest price ever paid for commercial property larger than 10,000 square feet in New York City. Vornado bought a controlling 49.5 percent interest in the office condominium for $80 million in December 2011, and took the remaining 40,742-square-foot retail condo for $707 million in July 2012.

The retail space formerly occupied by the NBA Store sold for $324 million, or $8,361 per square foot, to the Spanish retail giant. The space will serve as the new flagship store for Zara. The rest of the building's retail space, currently leased to Uniqlo and Hollister, is also on the market. The purchase price for the Zara space includes the early termination of the NBA Store's lease.

The Japanese fashion retailer signed a 15-year lease for $300 million, reportedly a record for retail space in the city. The reported asking rent was $30 million per year; the tenant will pay roughly $20 million per year. Uniqlo also has a location in Soho.

A 49 percent stake in the building's retail space sold for $525 million. Kushner will continue to own 100 percent of the office portion of the tower, which was acquired last year for a record $1.8 billion.

The building, which includes 84,855 square feet of retail space on the lower levels, sold for $1.8 billion, or $1,200 per square foot. Tishman Speyer Properties and an investment group bought the building in 2000 for $518 million. The transaction represents the largest single asset sale to date in New York City.
